ELECTRIC POCKET AND NIGHT LAMP.

Application filed April 19, 1922. Serial No. 555,652.

To all whom it may concern:

Be it known that 1, PAUL ROMBAGH, a citizen of Germany, residing at Karlsruhe i B, Germany, have invented a new and useful Electric Pocket and Night Lamp, of which the following is a specification.

This invention relates to improvements in electric pocket and night lamps, and its object is to provide an improved lamp, which can be placed on the table, hung on the wall for use during the night, or can conveniently be carried in the pocket.

The main novelty of the lamp resides in the fact that it is so arranged that light pressure applied to the lamp bulb, causes the same together with its socket, to be depressed into the casing, whilst the lamp is simultaneously switched oif, the circuit being broken. Means are also provided, such as for example, a press button or the like, for releasing the mechanism which holds the socket in its depressed position, the lamp being thereby raised to its normal position by spring pressure, the circuit being at the same time closed, and the lamp switched on. I

When the bulb is in the depressed position, any liability to crush it when carried in the pocket, or during transport is obviated, whilst at the same time, the space required by the lamp and its packing for storage or transport purposes, is considerably less than would be the case if the bulb were in a projecting position at the top.

A further advantage of a lamp constructed according to the present invention, is that owing to the position of the bulb on the casing, the light is better able to spread, than is usually the case.

With this and other objects in view, the invention consists substantially in an electric pocket and night lamp), having means for enabling the lamp bul to be depressed into the casing by slight pressure on the bulb, means for retaining the lamp and bulb in its depressed position, means for causing the circuit to be broken when the bulb is thus depressed, means for raising the lamp from its depressed to its normal position, and means for closing the circuit when the bulb is in its raised position.

The invention is carried out as follows, and a preferred form of construction is illustrated in the accompanying drawings, in which Fig. 1 shows an axial longitudinal section of a lamp according to the invention, without the battery and the bottom of the casing,

Fig. 2 shows a front elevation,

Fig. 3 shows a cross section on the line 33 Figs. 1 and 2, a

position by means of a sheet metal lever e engaging with a groove, in a socket a, and whose upper end projects through a slot in the cylinder d. In this position, the lamp is switched off as the circuit is broken between f and g. f is a metal disc secured to the socket abetween two insulating discs, and in contact with the contact plate of the bulb b by a rivet 7. The metal disc 7 is provided with a lateral extension, projecting laterally through a slot in the cylinder d, and bent around a similar extension of the upper insulating disc. 9 is an angular metal member, conductively connected to a contact spring h adapted to receive one pole plate of the battery. The member 9 and spring h, are secured to a cover plate i, which is riveted to the front wall of the casing c. To the cover plate 6 there is pivotally connected at k the lever e, and near the bottom thereof, there is secured a blade spring Z. At the free end of this spring which engages over the lower end of the lever e, is mounted a button m, guided in a hole in the front wall of the casing, and having its conical lower portion engaging ina slot in the lever. If this button is pressed downwards, the lever (2 will be turned in such a manner, by the lateral pressure of the lower portion of the button on the lower end of the lever, that the upper end of the lever is disengaged from the socket a. The latter will then be pressed back into the position shown in Figs. 1, 3 and 5, by the upper horizontal arm 0 the wire spring a secured to the cover plate 71, the said upper arm engaging with a lug 0, provided on the socket, and guided in a slot in the cylinder d. The incandescentbulb b will then again project from the casing o. In this position the lamp is switched on as the extension of the metal disc f is in contact with the angular member The spring a, of which the upwardly directed inclined arm passes through a hole in the lever e,"thu s also serves. to hold this lever in engagement with the socket a.

I claim 1- 1. An electric pocket lamp comprising a casing, a cylinder provided in the front of the casing and at right'anglesthereto, a socket slidab'ly disposed ithin said cylinder and a bulb mounted in said socket, whereby the bulb and socket may be depressed into said cylinder, means within th lamp casing 'for retaining" the bulb and socket in their depressed position, manually operated means disposed on the outside of the casing to release said retaining means, spring means for raising said socket and bulb from their depressed position and holding them in their raised position, and means for causing the circuit'to be closed when the bulb is in its raised positionfand broken when it is, depressed. 2. An electric pocket and night lamp, having means f'orfenab-ling the "lamp bulb to be depressed into the casing by slight pressure on the bulb, means for retaining the lamp and bulb in depressed position, and comprising asocket, a lever engaging with a groove in the socket, said lever being adapted when depressed against spring pressure, to release said socket, and enable it to resume its raised or normal position by means of spring pressure, means for raising the lamp fromits depressed to its normal position and means for causing the circuit to be closed when the bulb is in its raised position and broken when it is depressed.

3. An electric pocket and night lamp, having means for enabling the lamp bulb to be depressed into the casing by, slight pressure on'the bulb, means for retaining the lamp and bulb in depressed position, means for raising the lamp from its depressed to its normal position, and means for breaking of the circuit when the bulb is depressed and forclosing the circuit When the bulb is in its raised position and comprising a press button disposed on the exterior of the cas ing, and adapted When depressed to cause the socket and lamp bulb to be raised to their normal position.

In Witness whereof I aflix my signature.
